3. Storing CO2 in the seabed

In order to prevent carbon dioxide from fossil fuel burning accumulating in the air, people have tried to store the excess CO2 in large, porous rock structures under the sea.

Use the Internet to find out whether these attempts have been successful, try seach terms such as "CO2 storage" AND "sea floor”.

Do you think this is a good way to reduce the Enhanced Greenhouse Effect?
